I was riding in a car with my brother, and we saw all of the street lights and people's homes turn dark. The power came back on just as we were approaching an intersection, and a transformer on a power pole blew out, sending sparks all over the road. At the same time, my brother shouted "Wow, Look!", pointing his attention to a series of extremely bright green flashes that filled the entire sky. We couldn't see exactly where it was coming from, but it seemed like it was somewhere off the coast of the island.
